Mg + 2HCL -> MgCl2 + H2
24g 2moli
a) Mg + 2HCl -> MgCl2 + H2
36 g x=?
x = (36 x 2)/24 = 72/24=3 moli HCl
Cm=n/Vs =>3moli/0,3L=30moli/3L=10moli/L=10M
24g 22,4L
b) Mg + 2HCl -> MgCl2 + H2
36g y=?
y=(36 x 22,4)/24=33,6L H2
24g 95g
c) Mg + 2HCl -> MgCl2 + H2
36g z=?
M MgCl2= 24+35,5x2=24+71=95g/mol
z=(36x95)/24=142,5 g MgCl2
